I installed this on my West Wight Potter 15. Extension was easy to install but requires drilling a 7/16" hole in the tiller. This is an oddball size and bigger than I anticipated. Hopefully there is enough wood left! It does help reduce fatigue since I don't have to reach out as far to control the tiller. A little awkward to use but I am getting used to it. The twist lock is a little sticky. Hopefully it'll loosen up in time.
